PGT Sparta Aluminum Sliding Glass Door SGD4130A

PGT's value-tier aluminum impact line on the 4000-series platform.

Value-tier aluminum impact sliding door supporting up to 4 panels on 2 tracks or 3 panels on 3 tracks. Stainless and steel tandem rollers, LMI for HVHZ.

Impact Rating LMI Design Pressure +55/-65 psf Glazing Impact-resistant glass Florida Made in Florida

Impact protection, built for South Florida

The SGD4130A is the sliding door in PGT's value-tier Sparta line, the budget way to put an impact-rated patio opening in an HVHZ home. It runs up to four panels on two tracks, or three on three, with keyed-lock hardware and stainless and steel tandem rollers, and it carries the LMI impact rating Miami-Dade and Broward require. The configurations cover the common patio and lanai openings without the premium panel counts or sizes of the flagship doors.

Armor Pro specs the SGD4130A when a cost-driven full-home replacement still needs a code-compliant slider and the opening is a standard residential size. For wider spans, more panels, or the slimmest sightlines, the step up is the WinGuard Aluminum SGD770A; the trade is price for range.

Frequently Asked Questions

The SGD4130A is the sliding glass door in PGT's value-tier Sparta line, the budget way to put an impact-rated patio opening in a South Florida home. It supports up to four panels on two tracks or three panels on three tracks, with keyed-lock hardware and stainless-steel and steel tandem rollers. We install it on standard residential patio and lanai openings that need a code-compliant slider without the premium panel counts of the flagship doors.

Yes, the SGD4130A is LMI impact-rated and HVHZ-approved, built with impact-resistant glass so it carries the rating Miami-Dade and Broward require for a patio opening. That makes it a true hurricane-code slider rather than a non-impact door. We'll confirm the current approval that applies to your configuration and opening at quote.

In its by-pass configuration each panel runs from about 36 by 54 inches up to roughly 40.625 by 98 inches, for a total opening up to about 194.6 square feet, and the door carries a design pressure of +55/-65 psf. The frame depth ranges from 4.875 to 6.75 inches depending on the configuration. For wider spans, more panels, or the slimmest sightlines, the step up is PGT's WinGuard Aluminum SGD770A; we'll confirm what fits your opening at quote.

The SGD4130A uses PGT's Energy Shield Max impact glass on a 7/16-inch PVB interlayer, with a U-factor of 1.05, an SHGC of 0.23 to 0.26, and visible transmittance up to about 0.52, plus a condensation resistance rating of 15. The laminated impact glass also helps cut outside noise across a large patio opening. For a sun-facing lanai, the lower-SHGC option keeps heat gain down, and we'll review the choices at quote.

The SGD4130A comes standard with a keyed lock, raised and recessed handle options, stainless-steel and steel tandem rollers, and stainless-steel assembly screws for corrosion resistance in coastal air. It's offered in White and Bronze finishes with a 1-inch flat grid option. We coordinate the door finish and handle style with the rest of your Sparta windows so the patio opening matches the home.

There's no flat price, because the installed cost depends on the panel count and track configuration, the overall opening size, the glass package and grid, the finish, and the condition of the existing opening. A four-panel patio door is a bigger job than a two-panel one. Armor Pro gives a free, no-obligation estimate; we'll measure the opening and price the SGD4130A for your project.

Yes. Sparta is PGT's value-tier aluminum impact line, large-missile impact-rated and eligible for the High-Velocity Hurricane Zone in Miami-Dade and Broward. The glass is the same laminated impact glass the premium lines use, and the approvals are real — the line simply trims the premium sizes, finishes, and high-pressure configurations to hit a lower price. The exact rating depends on the opening, which we confirm on the quote.

What you give up with Sparta is range, not code compliance. Sparta covers the core operation styles — single hung, horizontal roller, picture, architectural shapes, and a sliding glass door — in white and bronze only, with block-and-tackle balance hardware and a narrower set of sizes and design pressures. WinGuard Aluminum adds more colors, larger sizes, higher pressures, and a broader catalog including casements, awnings, and French doors. We reach for Sparta when impact compliance is required but the budget is the binding constraint.

PGT has built impact windows and doors in Venice, Florida since 1980 and is the largest impact-window and -door manufacturer in the country. It was the first company to develop impact-resistant products that met Miami-Dade County's hurricane code after Hurricane Andrew, and the line is engineered specifically for Florida conditions. PGT is now part of the MITER Brands family, alongside WinDoor, ECO, and NewSouth, but the products are still made in Florida under the PGT name.
